Patent CA-2084451-A1 (CA)
Title: Polyimide surfaces having enhanced adhesion
Inventor: MURRAY CAMERON T
IPC: B32B7/10
Filed: 1992-12-03
Abstract: POLYIMIDE SURFACES HAVING ENHANCED ADHESION            ABSTRACT OF THE DISCLOSURE      The invention provides a polyimide substrate bearing thereon a disordered amorphous surface layer that provides improved adhesion when said polyimide substrate is used in polymer or metal laminates, wherein said surface layer is formed by the process of:      a)   providing a polyimide substrate having an ordered amorphous surface zone, and b)   irradiating at least a portion of the depth of said ordered amorphous surface zone with radiation from a pulsed energy source that produces pulses of sufficient duration and intensity to heat a portion of said surface zone to a temperature above the glass transition temperature but below the decomposition temperature, thus transforming said zone into an amorphous surface layer, c)   rapidly quenching said amorphous layer to a temperature below the glass transition temperature before the molecules comprising said disordered amorphous surface layer can reorient to the ordered amorphous state. The amorphous surface layer has a chemical composition unchanged from and identical to that of the ordered amorphous bulk phase but having physical characteristics that are different from that of the bulk phase. The solubility, coefficient of friction, antireflectivity, and anisotropic conductivity are greater and the density, birefrengence, and ultraviolet polarization are less in the amorphous layer than in the ordered amorphous bulk polymer.

Patent CA-2089431-A1 (CA)
Title: Shock absorber
Inventor: BELL STEPHEN H
IPC: F16F9/18
Filed: 1993-02-12
Abstract: An improved piston compression valve mechanism for a shock absorber includes a seal carrier member carried by the shock absorber piston and having a radially extending flange portion and a downwardly extending  cylindrical  portion,  an  o-ring  seal mounted between upper and lower radially extending arms  on the  flange portion,  and a  coil  spring mounted on the piston above the seal carrier member. The lower arm of the flange portion has an inner downwardly  facing  surface  adapted  to  engage  an upwardly facing valve seat on the piston, and the upper arm of the flange portion has an upwardly facing surface in force transmitting contact with the lower end of the coil spring.  The cylindrical portion of the seal carrier member is provided with a  plurality  of  flow  openings  spaced  about  its circumference and along its axial length which are normally in a closed position against the piston. During a compressive movement of the shock absorber, fluid  in  the  compression  chamber  of  the  shock absorber  increases  its  pressure  on  the  outer downwardly facing surface of the flange portion, causing the seal carrier member to slide upwardly on the piston initially without spring resistance and then against increasing spring resistance, thereby gradually exposing the flow openings so as to permit fluid to move from the compression chamber to the rebound chamber in the shock absorber.  The improved compression valve mechanism is dependent on fluid pressure, rather than fluid viscosity, resulting in a valve mechanism that reduces shock absorber fade at high fluid temperatures.

Title: A procatalyst composition containing substituted maleic of fumaric acid esters as electron donor for olefin polymerization
Inventor: IISKOLA EERO
IPC: C08F4/60
Filed: 1992-10-01
Abstract: It is known that an electron donor together with a compound of tetravalent titanium on a magnesium halide carrier is us-able if it is a mono- or polyester of an unsaturated polycarboxylic acid in which at least two carboxyl groups are joined to conti-guous carbon atoms which form double bonds. It has now been observed that activity and stereospecificity increase if at least one of the said carbon atoms, or a carbon atom joined thereto by a double bond, is substituted by a hydrocarbon group having 1-20 carbon atoms. Maleic and fumaric acid esters substituted with the said hydrocarbon group can be mentioned as examples.

Abstract: A baffle system for use in a clarifier tank having a tank bottom, a periphery and a substantially vertical peripheral wall bounding the interior of the tank is formed by a plurality of individual and cooperatively-engageable baffles mounted on the peripheral tank wall. Each baffle includes a panel member that downwardly slopes from the peripheral tank wall toward the interior of the tank and the tank bottom and terminates at a lower ledge disposed in spaced relation above the tank bottom. A first lateral end of the panel member unitarily carries an end bracket securable to the peripheral wall for supporting the panel member in a cantilevered fashion. The plural baffles are disposed in end-to-end relation about the peripheral tank wall such that the second lateral end of the panel member of each baffle is secured to the end bracket of the next-adjacent baffle whereby each end bracket supports the panel members of each set of two immediately-adjacent baffles on the peripheral wall. The resulting baffle system provides a smoothly continuous, inwardly and downwardly sloping surface along which solids precipitated from the liquid-solid suspension contained in the clarifier tank are gravitationally-directed to the tank bottom.
